A hybrid-type chassis part (10; 10'; 10''; 10'''; 30) has a support structure component (11; 11'; 11''; 11'''; 31) made of a first material and a reinforcement component (12; 12'; 32) made of a second material. The reinforcement component is designed so that in addition to the increasing of rigidity properties of the support structure component (11; 11'; 11''; 11'''; 31) the air resistance of the support structure component (11; 11'; 11''; 11'''; 31) is also reduced.
